Tennis princess Maria Sharapova has confirmed herself her romantic relationship with Bulgarian tennis star Grigor Dimitrov.

Right after Dimitrov, 21, the tall, dark and handsome Bulgarian from the city of Haskovo, who has long been seen as the next big thing in tennis, defeated World Number 1, Novak Djokovic, the couple was spotted on a romantic walk in Madrid.

Dimitrov and Sharapova were seen and caught on camera kissing, hugging and holding hands, which put an end to the endless rumors of their intimate relationship.

Meanwhile, the former number 1 Sharapova scored Friday evening an easy win with 6:2 and 6:4 against number 51 Kaya Kanepi from Estonia.

After winning the quarterfinal in Madrid, Sharapova joked about the revelation by writing on camera lens: "How did you catch us???" with a handy marker, smiling all the way.

Rumors the two are dating have circulated for a while now, but both have firmly denied them. They kept explaining they were very happy with their "significant other," but never mentioned a particular name.

After the faceoff with Djokovic, Dimitrov said in an interview that his girlfriend told him before the game "several words that he would never forget" that boasted his spirit and helped him score the historic win.

"I will keep the exact words secret, but I want to thank her," he explained.

Dimitrov also said his favorite view in the entire world was the one from his girlfriend's villa. Sharapova owns a luxurious vacation home in Malibu with a view of the Pacific.

After defeating Djokovic, Dimitrov lost to Switzerland's Stansislas Wawrinka and was eliminated from Madrid Open.

Sharapova will face another former number 1 - Ana Ivanovic for a place in the final.
